Dyno results on 150 shot of N20
Went to the dyno today. Did serveral passes. In contrast to the numbers that Crank and Chrome posted for their stock C5 Convertible, I think I did well.
Crank and Chrome stock- 297 HP unsure of Torque
My C5: 321.7 HP /340.9 Torque (see Mod list)
My C5 on 100 shot nitrous with 150 fuel jet: 403.7 HP/ 511.3 Torque
My C5 on 150 shot nitrous with 150 fuel jet 443.3 HP/514.9 Torque
I have the screen removed in the MAF. I think I would have gotten bigger gains if it was in. I am going to replace it with a stock MAF tomorrow.
Not bad considering I dont even hit the juice till 3400 RPM.

You should be happy with those results considering your mods...

Great numbers but doesn't NX rate their jets for RWHP? If so, you'd might consider checking your nitrous filter? What was your bottle pressure? Maybe it had to do with you spraying at 3400? JUICE RULES :D

Actually I think I may have toasted a plug. My friend dynoed his N20 Mustang today and got a graph that was jagged not smooth. I go the same graph. I thought it was because I removed my MAF screen. My mustang friend pulled his plugs and he toasted #2. I'm pulling mine tomorrow morning.. I'll keep you posted.

Changed the plugs this morning. All looked good. I went from the autolites to Boshe super plugs (copper). I contacted NX to see why I only got 120 hp out of the 150 jets. I think I need to change my MAF to one with a screen. I removed my screen sometime ago and I think its making my curve a little choppy.

Did you check your nitrous filter? Do you have a MAFT and did you autotap your runs? You may be running to rich thus robbing some horsepower? Let us know.

Nitrous filter is okay. I only had a wideband O2. Did not have a ATAP. I'm going to see Nate@xtreme today. Hopefully he can lend some opinion. The wideband O2 did show that I was a little on the rich side, but I thought that was good since I was spraying.

I had the 100 N2O and 150 fuel because I was pinging at low RPM's. Better to have too much fuel than not enough. After we put it on the dyno, we switched to the 150 N2O.
